High Efficiency Gas-Fired Modulating Condensing BoilerConvertible (Floor or Wall)

Residential Gas Modulating Condensing Hot Water Boiler

The increased efficiency of the 97gb could save you over 40% on your heating bill each year. If you pay $1,800 annually to heat your home, you could save as much as $720 per year.

- 95% AFUE- Sealed Combustion-*Built-in Outdoor Temperature Reset

That’s $3,600 over 5 years!†

The 97gb features 95% AFUE. Just add up the savings:

(*A factory standard Outdoor Temperature Reset adjusts water supply temperature for best possible fuel economy based on actual seasonal conditions.)

Doesn’t your family deserve a new high efficiency home heatingsystem and all the comfort and peace of mind that come with it?

If you have kids or pets that play in the basement or utility room, the 97gb offers optional wallmount installation, freeing up valuable floor space and easing ground level safety concerns.Since most of us have better things to do than fumble with the thermostat, the 97gb has an advanced microprocessor control that continuously monitors supply and return watertemperature, automatically adjusting the boiler’s output to keep the whole family comfortable.Another plus, when used with an indirect hot water heater, the 97gb quickly and efficientlyredirects heat when and where it’s needed. No standing around, waiting for hot water.

Winter is notorious for all sorts of life’s little gems. With the ever present threat of colds and flu, school closingsand delays, and an unpredictable daily commute - a runaway heating bill is the last thing you need. The truth is,most homeowners focus solely on utility costs and don’t actually think about their heating system until it needsto be repaired or replaced. One “No Heat” call to your local contractor can cost $300 or more, just to diagnosea problem and if your boiler has out-lived its warranty, you’ll be responsible for the full cost of parts and labor.

Your old low efficiency heating system can have an annual fuel utilization efficiency (AFUE) of70%. That means 70% of the energy in the fuel becomes heat for the home and the other30% escapes up the chimney and elsewhere. With an old inefficient boiler you could bethrowing away up to 30% of the money you spend on fuel each year.

97gb—Replacement/New Construction Ready Right Out of the Box

• 100% Compatible with Existing Piping – Flexible Piping (Top & Bottom) – Gas line connection can run out the top or be changed in the field to the bottom. Top and bottom supply/return options have 1-1/4” tapings. Boiler shipped with brass plugs for installer use.• Venting – Vent transition is constructed of PVC which is impervious to acidic condensate that pools and is corrosive to metals.

Simplified ElectricalConnections (120V,ArgusTM Control, LowVoltage Terminal Strip)

Leveling legs for floor mount applications included.

The Control Interface features easy-to-understand text display, remote mount option and simple 2 wireconnection. When the cover is on the unit, the control interface is protected by a smoke plastic hingedcover. A cover insert is standard for use with the remote mount option.
